As someone who grew up when most manufactures "recommended" only a 5W30 or 10W30 at most (during summer), i was talking to a 74 year old guy the other day that runs 20W50 in his jeep straight 6, i almost dropped to the floor. I could NEVER imagine running something that thick. It seems so out of place in today's engines, unless you have a built turbo, or a Diesel, i cant see any reason to run a motor oil like a 20W50. I kinda even think 5W30 is "old" school with oils like Toyota 0W16 on the market.
I'm even having a hard time using 5W30 in the Elantra, because Hyundai "recommend" a 5W20. (with 5W30 and 10W30 options under certain severe conditions..) I believe the thinner oil has better heat transfer, and flows quicker to the top of the motor on start ups.
I've never seen a engine blow because of thin oil, even on the high revving 3.5L Honda V6 thats in the family, its seen nothing but M1 5W20, and it is smooth as silk even with 214K miles on it.
I also believe a thicker oil is a band aid for loose engine clearances, or a neglected high mileage motor, and is not needed if it has been taken care of.
What are your thoughts on this? am i wrong in my thought process lol?
Thanks!.
